Descriptive Statistics

Origin provides the following tools to help you summarize your continuous and discrete data.

Descriptive

The Statistics on Columns/Rows operation performs column-wise/row-wise descriptive statistics on selected worksheet data.

  • Statistics on Columns
    Performs column-wise descriptive statistics on grouped or raw data.

  • Statistics on Rows
    Performs row-wise descriptive statistics to generate statistics for rows in worksheet.

Frequencies

  • Discrete Frequency
    Discrete frequency analysis is one common method to analyze discrete variables. It counts the frequency of discrete data, including percentage and cumulative percentage.

  • Frequency Counts
    The function computes the frequency counts for 1D data and help to produce histogram in desired way.

Histogram with distribution curve
2D histogram
  • 2D Frequency Count/Binning
    A useful tool to compute the frequency counts and plot 2D histogram for 2D/bivariate data.

Normality Test

A normality test is used to determine whether sample data has been drawn from a normally distributed population (within some tolerance).

Six different normality tests are available in Origin:

  • Shapiro-Wilk
  • Kolmogorov-Smirnov
  • Lilliefors
  • Anderson-Darling
  • D'Agostino's K-Squared
  • Chen-Shapiro

Correlation coefficient report

The correlation coefficient, also called the cross-correlation coefficient, is a measure of the strength of the relationship between pairs of variables. Origin provides both parametric and non-parametric measures of correlation.

  • Pearson's r Correlation
  • Spearman's Rank Order Correlation
  • Kendall's tau Correlation

Detecting Outliers

An outlier is an observation that is dramatically distant from the rest of the data. Origin provides two tools to help detecting the outliers.

  • Grubbs Test
  • Dixon's Q-test
